Do not place the thermostat on the inner side of a poorly insulated exterior wall.

Always install the thermostat at least 50 cm from windows and doors, due to draft, when using regu-lation in: floor and room mode or room alone mode.

Do not place the thermostat in a way that it will be exposed to direct sunlight.

DEVIreg™ Smart

9Installation Guide

Note: A floor sensor is recommended in all floor heating applications and mandatory to thin mats and under wooden floors to reduce the risk of over-heating the floor.

• Place the floor sensor in a protecting plastic conduit in the floor construction in an appropriate place, where the floor is not exposed to sunlight or draft from door openings.

• Equally distant and >2 cm from the heating cables on both sides.

• The conduit should be flush with the floor surface, countersink the conduit if neces-sary and possible.

• Route the conduit to the connection box.

• The bending radius of the conduit must be min 50 mm.

display module, e.g. using a screw-driver; it will be possible to set the maximum floor temperature up to 45°. Furthermore, it will be possible to use only a room sensor. However, this option is not recom-mendable due to an increased risk of overheating the floor.

IMPORTANT: When the ther-mostat is used to control a floor heating element in connection with a wooden floor or similar material, always use a floor sensor and never set the maximum floor temperature to more than 35°C.

19Installation Guide

Note: Please contact the floor supplier before changing the maximum floor temperature and be aware of the following:

• The floor temperature is measured there, where the sensor is placed.

• The temperature of the bottom of a wooden floor can be up to 10˚C higher than the top.

• Floor manufactures often specify the max. tempera-ture on the top surface of the floor.
